Yes, ther eis. There are actually many possible  solutions.

Example 1: You can put all settings you want in a  script,  create  a
script  image  from  it,  and place this in the flash sector directly
following the U-Boot image (which means you can just cat  the  images
and write them to flash in a single programming operation). Have your
default  bootcmd run this script using the autoscr command. Note that
the script can then also define a new bootcmd setting.

Example 2: You can put your U-Boot environment in the flash sector(s)
directly following the U-Boot image ...
